A squall line developed across central Iowa during the overnight hours and moved east.  As the squall line entered southeast Iowa, it began to bow out and raced across Jefferson, Henry, Louisa, and Des Moines Counties causing extensive damage.  The bow echo crossed the Mississippi River and continued across Henderson, Warren, and Mercer Counties before weakening.  The squall line did manage to produce isolated severe damage in Bureau and Putnam Counties in Illinois.  The far southern edge of the squall line managed to produce isolated to scattered severe reports across Northeast Missouri, Lee County Iowa, and Hancock and McDonough counties in Illinois.  Scattered thunderstorms that developed in the near tropical atmosphere ahead of the squall line produced isolated severe reports.

Initial damage began from Libertyville to about 3.7 miles northwest of Fairfield.  The high winds lasted roughly 10 minutes at any one location.  The Fairfield Airport measured 70 knot (81 mph) winds from 1031 to 1033 CST when power was lost.  Extensive damage occurred in the city of Fairfield with trees and power poles down along with water ponding on roads from heavy rainfall.  No additional damage reports were received east of Fairfield, but it is likely that sporatic damage occurred in an east northeast path to the Jefferson/Henry county line along and just north of the bow apex.  Based on that assumption, the following times have been established for affected cities (all times CST); Libertyville 1027-1037, Fairfield Airport 1031-1041, Fairfield 1033-1043, Perlee 1040-1050, Salina 1045-1055, East Pleasant Plain 1048-1058, Germanville 1050-1100, and Merrimac 1053-1103.

Bow echo entered Louisa County from Henry County and affected mainly the southern part of the county before crossing the Mississippi River into Illinois.  Trees and power poles down were the primary damage but several homes and buildings were damaged by falling trees, had shingles removed, or suffered partial roof failure.  A car dealership under construction at the junction of U.S. 61 and highway 78 was destroyed or 4.2 miles east of Morning Sun.  Pictures indicate all the debris laying in one direction.  However, the manager of a nearby convenience store reported seeing a funnel.  Radar data is in conclusive but the location is on the leading edge of the squall line and is likely a gustnado.  Based on radar, the following times are established (all CST); Morning Sun 1138-1148, 4.2E of Morning Sun 1143-1153, Oakville 1147-1157.

The southern part of the bow echo or perhaps a new bow echo moved across Des Moines County from Henry County.  A large number of trees were downed along with power poles with some trees as big as 2 to 4 feet in diameter with the main damage in West Burlington and Burlington.  Radar data does indicate the stronger winds were along and north of the apex of the main bow in Louisa County.  Tornado like damage was reported in Beaverdale with a funnel cloud reported 1S of Beaverdale.  The following times have been established based on radar data (all CST); Pleasant Grove 1129-1139, Mediapolis 1136-1146, Danville 1138-1148, Beaverdale 1143-1153, West Burlington 1148-1158, Burlington 1155-1205.
